This seems like it should be doable, but it seems just the $form object itself is included in the filter, not the entry data? Is that correct?
Yes, in the free add-on (and the pro add-on with Direct mode), the transaction happens before the entry is created. You can catch the form post to get the field value though. Look in $_POST (e.g. with xdebug, or log to the WP debug.log) to see what to pluck from that array.

Hi @cjwebdev,
Yes, I got it working.
1. I added a 'single-line text' field to the Form so the user could specify a Reference Number.
Note: The field had an ID of 5 - see attached image:
Your field will likely have a different ID. Keep that in mind as you will be using the ID in the filter.
2. I added the following to the functions.php:
add_filter('gfeway_invoice_ref', function($invoiceReference, $form) {
//Check that we are applying the filter for the correct form (form ID 3) using and that the correct field (field ID 5) is set.
if( $form['id'] == 3 && isset($_POST['input_5']) ){
// If it is, set the $invoiceReference to the value of the Field.
$invoiceReference = $_POST['input_5'];
}
return $invoiceReference;
}, 10, 2);
Thanks @samheavyside,
That's great you can access the $_POST object so easily.
Really appreciate you sharing - have a great day!

Hi.
This looks simple enough, but I am wondering how I would use the data from the submitted form as the invoice reference (I'm using the free version of the GFEway plugin).
Example:
If I have a simple Text field - Invoice Ref: ________
How can I use the value entered as the InvoiceReference?
This seems like it should be doable, but it seems just the $form object itself is included in the filter, not the entry data? Is that correct?
